The main aim of the "Ecosystems, know to protect!" project is to disseminate scientific and technological knowledge, involving students and the rest of the educational community in science activities so that they have the tools they need to make informed and conscious choices, thus contributing to the sustainability of the planet. The activities organised were in line with this objective: construction and promotion of an ecological pond in conjunction with the CMPF Environmental Observatory; study of the identification of plastics and their impact on marine ecosystems, production of bioplastics; construction of a pollinator bed; identification of invasive species in conjunction with FAPAS; investigation into the causes and consequences of global warming; identification of biodiversity between tides; etc).
